target relevance
Interferon-gamma (IFN gamma) is a cytokine that plays physiologically important roles in promoting innate and adaptive immune responses. The absence of IFN gamma production or cellular responsiveness in humans and experimental animals significantly predisposes the host to microbial infection, a result that validates the physiologic importance of this cytokine in preventing infectious disease.

Protein family
Type II (or gamma) interferon family
FUNCTION: Type II interferon produced by immune cells such as T-cells and NK cells that plays crucial roles in antimicrobial, antiviral, and antitumor responses by activating effector immune cells and enhancing antigen presentation (PubMed:16914093, PubMed:8666937). Primarily signals through the JAK-STAT pathway after interaction with its receptor IFNGR1 to affect gene regulation (PubMed:8349687). Upon IFNG binding, IFNGR1 intracellular domain opens out to allow association of downstream signaling components JAK2, JAK1 and STAT1, leading to STAT1 activation, nuclear translocation and transcription of IFNG-regulated genes. Many of the induced genes are transcription factors such as IRF1 that are able to further drive regulation of a next wave of transcription (PubMed:16914093). Plays a role in class I antigen presentation pathway by inducing a replacement of catalytic proteasome subunits with immunoproteasome subunits (PubMed:8666937). In turn, increases the quantity, quality, and repertoire of peptides for class I MHC loading (PubMed:8163024). Increases the efficiency of peptide generation also by inducing the expression of activator PA28 that associates with the proteasome and alters its proteolytic cleavage preference (PubMed:11112687). Up-regulates as well MHC II complexes on the cell surface by promoting expression of several key molecules such as cathepsins B/CTSB, H/CTSH, and L/CTSL (PubMed:7729559). Participates in the regulation of hematopoietic stem cells during development and under homeostatic conditions by affecting their development, quiescence, and differentiation (By similarity). {ECO:0000250|UniProtKB:P01580, ECO:0000269|PubMed:11112687, ECO:0000269|PubMed:16914093, ECO:0000269|PubMed:7729559, ECO:0000269|PubMed:8163024, ECO:0000269|PubMed:8349687, ECO:0000269|PubMed:8666937}.
Subellular location
TISSUE SPECIFICITY: Released primarily from activated T lymphocytes.
SUBUNIT: Homodimer (PubMed:1902591). Interacts with IFNGR1 (via extracellular domain); this interaction promotes IFNGR1 dimerization (PubMed:8349687). {ECO:0000269|PubMed:1902591, ECO:0000269|PubMed:8349687}.
Post-translational modification
PTM: Proteolytic processing produces C-terminal heterogeneity, with proteins ending alternatively at Gly-150, Met-157 or Gly-161. {ECO:0000269|PubMed:3109913}.
